The company can sell all the units it can produce of either Product A or Product B. Product A has a unit contribution margin of $16 and takes two machine hours to make and Product B has a unit contribution margin of $18 and takes three machine hours to make. If there are 600 machine hours available to manufacture a product, how much more will the company earn if Product A is the only product produced than if Product B is the only product produced?
